That's not uncommon. When I consulted, I deducted mileage from my taxes. Part of that was saving all my gas receipts. All it takes is a bit of mindfulness, an envelop, and a filing cabinet (filing cabinet optional).

Yep, that's mine. The car has $6k in upgrades that are practically new, I know that's not worth a lot still on the car, but if I take that all off and sell separately I'm looking at about $4k there and can drop the price of the car to $37-38k which for a stock 08 with 6800 miles seems like it would be fair.
